RockResist: Care and Use Instructions

ROCKRESIST GEN1 ATHLETIC SOCKS: COMPREHENSIVE CARE & MAINTENANCE  GUIDE 

This document serves as the official care manual to protect the technical integrity of your  RockResist GEN1 Socks. The body of the sock consists of a durable cotton-terylene blend,  while the specialized, dual-configuration apron utilizes a high-performance polyurethane  (PU) debris barrier. 

⚠️ CRITICAL WARNING: NO MACHINE CYCLES 

The polyurethane apron relies on structural flexibility to snap into place and block trail  debris. Machine washing and tumble drying will rapidly destroy this component. 

• Thermal Delamination: Dryer heat permanently weakens the polymer structure.  This causes the polyurethane barrier to warp, crack, or peel away from the fabric  base. 

• Mechanical Stress: The twisting, stretching, and friction of a washing machine  agitator tears and overstretches the apron. This destroys its ability to hold its shape  against your heel collar.

Chemical Breakdown: Aggressive standard detergents strip away the chemical  stability of the polyurethane area over time. This makes it brittle or prematurely  sticky. 

CORE CARE INSTRUCTIONS 

Always use a strict Hand Wash and Line Dry routine. Take care not to aggressively scrub,  twist, or pull at the polyurethane flap itself. 

Hand Washing Steps 

1. Fill Basin: Mix a small amount of mild liquid detergent or specialized sports wash  into cold or lukewarm water. 

2. Soak Gently: Submerge the socks completely for 10 to 15 minutes to loosen trail  dirt. 

3. Agitate Fabric: Gently swish the socks around. Lightly rub the cotton-terylene heel  and toe sections only.

4. Avoid Twisting: Do not wring or twist the fabric forcefully to squeeze out water.  Press the socks against the basin wall instead. 

5. Clear Rinse: Rinse thoroughly under running cold water until all soap residue is  completely gone. 

Line Drying Steps 

1. Extract Water: Roll the socks flat inside a clean towel and press down gently to  absorb excess moisture. 

2. Hang by Toes: Clip the socks to the line by the toes rather than the elastic cuff to  protect the leg opening from stretching out. 

3. Avoid Heat: Dry completely flat or on a line away from direct, intense sunlight,  radiators, or active heat sources. Do not iron or dry clean. 

Neutralizing Stubborn Trail Odors 

• Dry Method (Baking Soda): Place clean, dry socks inside a breathable bag with 1  tablespoon of baking soda. Seal the bag overnight to absorb sweat odors and  volatile organic compounds (VOCs) without liquids. Shake the residue out the next  morning. 

• Wet Method (Sports-Wash Soak): Soak heavily soiled socks for 15 minutes in a  cold-water bath infused with an enzyme-based sports detergent or tech wash. This  safely strips away sweat oils without hurting specialized laminates. 

APPROVED TECHNICAL DETERGENTS 

Use cleaners that are residue-free, pH-neutral, and formulated without harsh  chemicals, heavy perfumes, or optical brighteners. Standard laundry detergents leave  behind chemical coatings that trap sweat odors. 

Note: Use only half a teaspoon of these highly concentrated formulas per hand wash basin. 

Cost Comparison 

The pricing below reflects current standard container options. Because hand-washing  single items uses significantly less detergent than a full washing machine cycle, your  actual cost per hand-wash will drop to just pennies per basin.
